The ketogenic (keto) diet is a low-carb, high-fat eating plan that shifts your body into ketosis, a metabolic state where fat becomes the primary fuel source. To maintain ketosis and maximize the benefits of the diet, it’s essential to focus on nutrient-dense, keto-friendly foods. In this guide, we’ll explore the best foods to help you stay in ketosis, from healthy fats to low-carb vegetables and protein sources.
Healthy Fats and Oils
Since fat is the main energy source on a keto diet, consuming the right types of fats is crucial. Healthy fats keep you full, support brain function, and help your body maintain ketosis.
Best Healthy Fats for Keto:
-
Avocados – Rich in monounsaturated fats and fiber
-
Olive Oil – A heart-healthy fat perfect for salads and cooking
-
Coconut Oil – Contains MCTs (medium-chain triglycerides) that promote ketosis
-
Butter and Ghee – Excellent sources of saturated fats for cooking
-
MCT Oil – A concentrated source of ketone-boosting fats
-
Nuts and Seeds – Almonds, walnuts, chia seeds, and flaxseeds are great low-carb options
Fats to Avoid:
-
Processed vegetable oils (canola, soybean, corn oil)
-
Margarine and hydrogenated oils (trans fats)
High-Quality Protein Sources
Protein is essential for muscle maintenance and overall health, but consuming too much can reduce ketosis by increasing glucose production. Stick to moderate protein intake with high-quality sources.
Best Protein Sources for Keto:
-
Fatty Fish – Salmon, mackerel, sardines, and tuna are rich in omega-3s
-
Beef and Lamb – Opt for grass-fed cuts for better nutrient content

Proteins to Avoid:
-
Processed meats with added sugars (honey-glazed ham, sweetened sausages)

Breaded or fried meats that contain high-carb coatings
Low-Carb Vegetables
Vegetables are an important part of a keto diet, providing essential fiber, vitamins, and minerals. The best choices are non-starchy, low-carb vegetables that won’t spike blood sugar levels.

Dairy and Dairy Alternatives
Dairy can be a great source of fat and protein on keto, but it’s important to choose full-fat, low-carb options.
Best Dairy Options for Keto:

Heavy cream (ideal for coffee and cooking)
